Definitions
- the present invention relates to a laundry care device with a Laugener Wegungs Surprise.
- a laundry care process in a laundry care appliance such as e.g. a washing machine
- a wetting phase takes place before the start of the washing phase, in which the dry items of laundry in the washing drum of the laundry care appliance are wetted with washing liquor.
- the washing liquor is usually heated to a desired washing temperature and the washing phase begins.
- the effectiveness of wetting the laundry with wash liquor depends on the amount of laundry in the washing machine. If the washing drum of the washing machine is completely loaded with items of laundry, during the wetting phase, only the outer area of the laundry which comes into contact with the wash solution will be sufficiently wetted. With a full loading of the washing drum with laundry, the inner region of the laundry located in the washing drum usually remains dry and is not adequately wetted by washing liquor. For this reason, in a full load of a washing machine, the inner area of the laundry often can not be sufficiently cleaned. It is the object underlying the invention to provide a laundry care device that allows a more efficient care of laundry.
- the invention is based on the recognition that the addition of a wash liquor with a higher detergent concentration and a higher temperature in a first period, compared to a wash liquor added in a second period, leads to a better wetting of the laundry. This achieves better care of laundry.

- the technical advantage is achieved that due to the higher temperature of the wash liquor and the higher concentration of the detergent in the wash liquor during the first period of the wash, compared to the second period of the wash, a complete wetting of the outer and inner region of the care Laundry with wash liquor is guaranteed.
- the first temperature of wash liquor in the first period is higher than the second temperature of wash liquor during the second time period.

- an additional third section is introduced in the first period of the washing process, during which an additional amount of wash liquor is supplied to the laundry.
- a first wash liquor is produced at a first concentration and a second wash liquor is produced at a second concentration.
- effective wetting of the outer and inner portions of the wash is achieved.
- the production of a further fourth wash liquor during a third portion of the first period of time supplies an additional amount of wash liquor to the laundry located in the laundry care appliance. By adding this additional amount of wash liquor, effective wetting of all areas of the laundry in the laundry care appliance is achieved in an effective manner.
- the fourth concentration of the fourth wash which may be supplied during the third portion of the first period, is less than the second concentration of the second wash, which is supplied during the second portion of the first period.
- concentration of detergent in the wash liquor which are supplied in the first, second and third portion of the first period, decreases continuously.
